Description

Technical Field

[0001] The present invention relates to a forming integrated device, in particular to a forming integrated device for fiber-based flexible energy storage capacitor materials, belonging to the technical field of electric material production. Background Art

[0002] With the rapid development of portable electronic devices and the intelligent wearable industry, developing high-performance flexible energy storage materials to power flexible electronic devices has become the current research focus. Among numerous flexible energy storage materials, fibrous supercapacitors (FSCs) are one of the best choices due to their good flexibility, long cycle life, high power density, small size, and light weight.

[0003] In the prior art, for example, the invention with the application number 202210931496.9 discloses a fabric-based self-integrated flexible supercapacitor and its preparation method. To solve the problems that the electrodes of the current coplanar supercapacitors are arranged on the same plane, resulting in lower areal capacitance and energy density of the capacitor device compared to traditional sandwich-type supercapacitors, and the size of the device increases significantly after series and parallel integration, affecting portability and flexibility, etc., a fabric-based gel polymer composite material is used as both the separator and the electrode fabric substrate to avoid the displacement of multiple layers of materials under repeated deformation, improving the structural compactness, electrochemical stability, and flexibility of the capacitor; and the fabric-based gel polymer composite material forms regular grooves on the surface, which not only increases the contact area between the electrode material and the gel electrolyte but also improves the interfacial interaction between the electrode and the gel electrolyte.

[0004] The prior art similar to the above application still has deficiencies: During the process of forming the capacitor material, multiple processes such as dipping - rolling - drying are required, and printing and drying operations are also needed after drying. Each step needs to be completed separately, which not only takes a long time but also makes the production process very cumbersome, seriously affecting the production efficiency of the material.

[0005] Therefore, a forming integrated device for fiber-based flexible energy storage capacitor materials is designed to optimize the above problems. Summary of the Invention

The forming process of the materials is more coherent, without complex operation steps, and the production and processing are more convenient and fast. By arranging impregnation guide rollers inside the impregnation tank and drying guide rollers inside the drying oven, and the impregnation guide rollers and the drying guide rollers are arranged in a staggered manner, the processes of multiple impregnation-rolling-drying can be continuously carried out, improving the impregnation rate of the fabric substrate. At the same time, the drying oven and the drying box are connected through a lower circulation pipe, a circulation fan and an upper circulation pipe, and the electric heater is located inside the drying box, and hot air circulation can be carried out, saving the production cost of the equipment. In addition, by controlling the speed of the circulation fan, the temperatures inside the drying oven and the drying box can be regulated, and the temperature inside the drying oven is lower than the temperature inside the drying box, ensuring the drying effect of the fabric substrate and the drying of the materials. By using a printing plate, an electric telescopic rod, a squeegee, a forming switch, a lifting assembly, a slurry adding assembly and a uniform discharging assembly, silk-screen printing operations can be carried out during use.

Detailed implementation manners

[0020] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.

[0021] As shown Figures 1-8 In the figure, this embodiment provides an integrated forming device for a fiber-based flexible energy storage capacitor material, including a base 1. One end of the top of the base 1 is provided with an impregnation tank 2. A leading roller 3 is rotatably installed at one end of the top of the impregnation tank 2. A plurality of impregnation guide rollers 4 are evenly and rotatably installed inside the impregnation tank 2. The impregnation guide rollers 4 are located on the same horizontal plane. A drying oven 5 is fixed to the top of the impregnation tank 2. A plurality of drying guide rollers 6 are evenly and rotatably installed inside the drying oven 5. The drying guide rollers 6 are located on the same horizontal plane, and the drying guide rollers 6 are staggered with the impregnation guide rollers 4. A plurality of sleeves 7 are evenly arranged at the bottom of the drying oven 5. The sleeves 7 extend below the liquid level inside the impregnation guide rollers 4. A pair of rollers 8 for clamping the fabric substrate are symmetrically arranged inside the sleeves 7. The fabric substrate inside the impregnation tank 2 is conveyed upward from below through between the rollers 8. A pair of trailing rollers 9 are symmetrically and rotatably installed at one end of the drying oven 5 away from the leading roller 3. A support table 10 is arranged at the middle position of the top of the base 1. A screen printing mechanism 11 is arranged on the top of the support table 10. A slurry preparation tank 12 is arranged at the bottom of the support table 10. A drying box 13 is arranged at one end of the top of the base 1 away from the impregnation tank 2. A winding roller 18 for winding the material is rotatably installed on the outer end face of the drying box 13 away from the impregnation tank 2. A winding motor is arranged at the end of the winding roller 18.

[0022] Overall working principle: Before use, first configure the impregnation liquid inside the impregnation tank 2 and the electrode slurry inside the slurry preparation tank 12. When using it for the first time, the end of the fabric substrate can be pre-treated with multiple impregnation-rolling-drying processes to obtain a fabric-based gel polymer composite material of a certain length, and then passed through the device. The fabric substrate will not cause excessive waste, only a section of the substrate inside the drying box 13 will be wasted. It is also possible to directly pass the fabric substrate through the device. At this time, the substrate from the winding roller 18 to the first group of impregnation guide rollers 4 will cause material waste due to incomplete impregnation. During normal processing, the substrate passes through multiple impregnation-rolling-drying processes and is discharged from the inside of the drying oven 5. The winding motor will intermittently control the winding roller 18 to wind a certain length of the substrate. This length is the length of the substrate on the side of a single impregnation guide roller 4 located inside the impregnation liquid. The substrate of a fixed length enters the top of the support table 10. The screen printing mechanism 11 is used to print the surface of the substrate and then reset. Since it takes a certain amount of time to dry the substrate inside the drying oven 5, the substrate will stay on the top of the support table 10 for a certain period of time after printing and be dried at room temperature. After the drying time of the substrate inside the drying oven 5 reaches, the winding motor will be started again to control the rotation of the winding roller 18, convey the printed substrate to the inside of the drying box 13 for drying, and after drying is completed, it will be wound around its surface when the winding roller 18 rotates again, completing the single-sided forming of the capacitor material on the substrate.

[0023] In this embodiment, an electric heater 14 is provided inside the drying oven 13. An upper circulation pipe 17 is provided between the top of the drying oven 5 and the drying oven 13. A lower circulation pipe 15 is provided between the bottom of the drying oven 5 and the drying oven 13. A circulation fan 16 is installed at one end of the lower circulation pipe 15 inside the electric heater 14.

[0024] Local working principle: During the drying of the fabric-based gel polymer composite material and the drying of the capacitive material, only a single electric heater 14 is used to provide heat sources for the interiors of the drying oven 13 and the drying oven 5. Additionally, since the drying temperature of the fabric-based gel polymer composite material is lower than the drying temperature of the capacitive material, during use, by controlling the rotation speed of the circulation fan 16, a certain temperature difference can be ensured inside the drying oven 13 and the drying oven 5, and at the same time, appropriate temperatures can be provided for the drying of the fabric-based gel polymer composite material and the drying of the capacitive material.

[0025] In this embodiment, a first stirring motor 201 is installed at the bottom of the impregnation tank 2 near one end of the leading roller 3. The output end of the first stirring motor 201 is equipped with a first stirring shaft 202. The first stirring shaft 202 is located inside the impregnation tank 2. A heating pipe 203 is provided at the bottom of the impregnation tank 2.

[0026] Local working principle: During the preparation of the polyvinyl alcohol-potassium hydroxide gel electrolyte, the first stirring shaft 202 is rotated and stirred by the first stirring motor 201, and the power supply of the heating pipe 203 is turned on to provide an appropriate temperature for the impregnation tank 2 to accelerate the preparation. Specifically, the mass ratio of polyvinyl alcohol (PVA) to deionized water is 1:5 to 1:10, the concentration of potassium hydroxide (KOH) is 2 to 5 M, PVA is stirred and dissolved at 80 to 95 °C, and after cooling to 40 to 50 °C, a KOH solution is added, and stirring is continued for 1 to 2 hours until a homogeneous gel is formed. The temperature of the impregnation tank 2 is maintained at 45 ± 2 °C.

[0027] In this embodiment, a second stirring motor 1201 is installed at the top of the slurry preparation tank 12. The output end of the second stirring motor 1201 is equipped with a second stirring shaft 1202. The second stirring shaft 1202 is located inside the slurry preparation tank 12. An ultrasonic disperser 1203 is installed on the side of the slurry preparation tank 12.

[0028] Local working principle: During the processing of the nano-carbon electrode slurry, the second stirring shaft 1202 is rotated and mixed by the second stirring motor 1201, and ultrasonic treatment is performed by the ultrasonic disperser 1203.

[0029] In this embodiment, the screen printing mechanism 11 includes a printing plate 1101, an electric telescopic rod 1102, a squeegee 1103, a travel switch 1104, a lifting assembly, and a slurry adding assembly. The printing plate 1101 is arranged in parallel on the top of the support table 10. An electric telescopic rod 1102 is installed at one end of the top of the printing plate 1101 close to the drying oven 13. The output end of the electric telescopic rod 1102 is installed with a squeegee 1103. Travel switches 1104 are provided at both the top and the bottom of one end of the drying oven 13 close to the support table 10. A lifting assembly for controlling the up and down movement of the printing plate 1101 is provided on the top of the drying oven 5, and a slurry adding assembly is provided on the squeegee 1103.

[0030] Local working principle: During the process of the fabric substrate being conveyed towards the top of the support table 10, the lifting assembly simultaneously controls the printing plate 1101 to move downward, and injects the nano-carbon electrode slurry onto the top of the printing plate 1101 through the slurry adding assembly. When the fixed-length conveyance of the fabric substrate is completed, at this time, the printing plate 1101 is completely attached to the fabric substrate. The printing plate 1101 contacts the travel switch 1104 at the bottom of the drying oven 13, controlling the automatic start of the electric telescopic rod 1102 to complete the printing of the substrate. After the printing is completed, the lifting assembly controls the printing plate 1101 to move up and reset. After the reset, the printing plate 1101 contacts the travel switch 1104 at the top of the drying oven 13 to reset the electric telescopic rod 1102.

[0031] In this embodiment, the lifting assembly includes a fixing plate 1105, a support plate 1106, a rectangular groove 1107, a sliding plate 1108, a first spring 1109, a sliding rod 1110, a second spring 1111, a first rack 1112, a first gear 1113, a pulley assembly 1114 and a vertical rod 1115. The fixing plate 1105 is fixed to the top of the drying box 5. A support plate 1106 is horizontally fixed to one side of the fixing plate 1105 close to the support table 10. A rectangular groove 1107 is formed inside the support plate 1106. A sliding plate 1108 is horizontally slidably arranged inside the rectangular groove 1107. A first spring 1109 is arranged between one end of the sliding plate 1108 close to the drying box 13 and the end of the rectangular groove 1107. Sliding rods 1110 are vertically slidably arranged on both sides of the sliding plate 1108. The bottom of the sliding rod 1110 is fixedly connected to the printing plate 1101. A second spring 1111 is arranged between the bottom of the sliding plate 1108 and the printing plate 1101. The sliding rod 1110 passes through the inside of the second spring 1111. A first rack 1112 is vertically slidably arranged at one end of the top of the sliding plate 1108 away from the sliding rod 1110. The bottom of the first rack 1112 is fixedly connected to the printing plate 1101. A first gear 1113 meshing with the first rack 1112 is rotatably installed at one end of the drying box 5 close to the printing plate 1101. A pulley assembly 1114 is arranged between the side of the first gear 1113 and the end of the rear guide roller 9. Vertical rods 1115 are symmetrically arranged on both sides of one end of the support table 10 close to the rear guide roller 9. Push rods 1116 are fixed to both ends of the squeegee 1103. The vertical rods 1115 are located on the extension lines of the push rods 1116.

[0032] Local working principle: During the conveying process of the fabric substrate, the rotation of the rear guide roller 9 will be driven. The rotation of the rear guide roller 9 will drive the first gear 1113 to rotate clockwise through the pulley assembly 1114. The first gear 1113 controls the downward movement of the first rack 1112, and further controls the downward movement of the printing plate 1101. After the fabric substrate moves a fixed length, the printing plate 1101 contacts the fabric substrate and no longer moves downward. After the electric telescopic rod 1102 controls the squeegee 1103 to complete printing, it will also move a certain length. At this time, the end of the push rod 1116 will contact the vertical rod 1115. Since the position of the vertical rod 1115 remains unchanged, it will control the sliding of the sliding plate 1108 inside the rectangular groove 1107, and at the same time drive the movement of the printing plate 1101, separating the first gear 1113 from the first rack 1112. Since the second spring 1111 is stretched during the downward movement of the printing plate 1101, after the first gear 1113 is separated from the first rack 1112, the second spring 1111 resets, controlling the upward movement and reset of the printing plate 1101. The push rod 1116 slides outside the vertical rod 1115 to consume the elastic potential energy of the second spring 1111, avoiding jitter after the printing plate 1101 is reset. After the printing plate 1101 is reset, the electric telescopic rod 1102 also drives the squeegee 1103 to reset. The push rod 1116 is separated from the vertical rod 1115, and the first spring 1109 controls the reset of the sliding plate 1108, and the first gear 1113 meshes with the first rack 1112 again.

[0033] In this embodiment, wear-resistant coatings are applied to the side of the vertical rod 1115 close to the push rod 1116 and the end of the push rod 1116.

[0034] Local working principle: The use of wear-resistant coatings can reduce the wear of the side of the vertical rod 1115 and the end of the push rod 1116.

[0035] In this embodiment, the slurry adding component includes a cylinder body 1117, a piston 1118, a push-pull rod 1119, a liquid discharge pipe 1122, a nozzle 1123 and a liquid inlet pipe 1124. The cylinder body 1117 is fixed at the bottom of the support table 10. A piston 1118 is vertically slidably arranged inside the cylinder body 1117. A push-pull rod 1119 is fixed to the top of the piston 1118. The push-pull rod 1119 slidably extends to the top of the support table 10 and is slidably connected to the printing plate 1101. One end of the bottom of the cylinder body 1117 is provided with a liquid discharge pipe 1122. The top of the liquid discharge pipe 1122 is provided with a nozzle 1123. There is a liquid inlet pipe 1124 between the bottom of the cylinder body 1117 and the slurry preparation tank 12. Check valves are provided on both the liquid discharge pipe 1122 and the liquid inlet pipe 1124. The nozzle 1123 is located on the squeegee 1103, and a uniform discharging component for controlling the reciprocating movement of the nozzle 1123 along the length direction of the squeegee 1103 is provided on the squeegee 1103.

[0036] Local working principle: During the downward movement of the printing plate 1101, the piston 1118 will slide downward inside the cylinder 1117 through the push-pull rod 1119, extruding the slurry extracted from inside the cylinder 1117 from the slurry preparation tank 12. The slurry passes through the drain pipe 1122 and then is discharged from the nozzle 1123 and falls onto the top of the printing plate 1101. Additionally, during the discharging process, the uniform discharging component controls the nozzle 1123 to move along the length direction of the squeegee 1103, ensuring the uniformity of the printing quantity.

[0037] In this embodiment, a first slider 1120 is fixed to the top of the push-pull rod 1119. A strip-shaped groove 1121 is formed along the length direction at the bottom of the printing plate 1101, and the first slider 1120 slides horizontally inside the strip-shaped groove 1121.

[0038] Local working principle: During the horizontal sliding process of the printing plate 1101, the first slider 1120 moves inside the strip-shaped groove 1121, and the printing plate 1101 can only control the vertical movement of the push-pull rod 1119.

[0039] In this embodiment, the uniform discharging component includes a reciprocating lead screw 1125, a second slider 1126, a second gear 1127, and a second rack 1128. The reciprocating lead screw 1125 is rotatably installed between the two ends of the squeegee 1103. A second slider 1126 is slidably installed on the reciprocating lead screw 1125. The nozzle 1123 is fixed to the second slider 1126, and the discharge port of the nozzle 1123 faces the printing plate 1101. Second gears 1127 are fixed to both ends of the reciprocating lead screw 1125. Second racks 1128 are vertically installed on both sides of the support table 10. The second racks 1128 are engaged with the second gears 1127, and the second racks 1128 are located on the side of the second gears 1127 away from the drying box 13.

[0040] Local working principle: During the downward movement of the printing plate 1101, at this time, the second rack 1128 is always engaged with the second gear 1127. Therefore, the downward movement of the printing plate 1101 will control the rotation of the second gear 1127. The second gear 1127 drives the reciprocating lead screw 1125 to rotate, controlling the second slider 1126 to drive the nozzle 1123 to slide. After the printing plate 1101 is attached to the substrate, the second slider 1126 moves from one end of the reciprocating lead screw 1125 to the other end. During the translational movement of the printing plate 1101, the second gear 1127 is also separated from the second rack 1128 and only re-engages after the printing plate 1101 moves upward and resets.

Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and concept of the present invention, makes equivalent substitutions or changes, all belonging to the protection scope of the present invention.
